She will be fine, I have had lots of dogs spay or neutered. Although I don't want to scare you but want you to watch the signs, I had a 1 year old kitty who did die because of spay, the doctor I am sure was drunk, from other people stories and nicked something or didn't close her up inside right and she bleed in side to death. Signs to watch for if she wants to be alone, hide from you, wont eat just and just weak the 2nd day . My cat hid from us and wouldn't eat. My vet said she is OK that what they can do, the 3 day she fell on floor in front of my husband and was so sick, I rushed her to vet she died 2 hours later after they worked on her. They made me go out back door with her. Just watch the signs. I just had Bad vet. I know your baby will be fine.
